Is Costco the first nation wide retailer requiring masks?
Face Mask Requirements
To protect our members and employees, effective May 4, all Costco members and guests must wear a mask or face covering that covers the mouth and nose at all times while at Costco. This requirement does not apply to children under the age of 2 or to individuals who are unable to wear a mask or face covering due to a medical condition.
The use of a mask or face covering should not be seen as a substitute for social distancing. Please continue to observe rules regarding appropriate distancing while on Costco premises. Thank you for your understanding and cooperation.
